can I create array inside formula node

[wayusoff]

I need to create and use array (multidimensional) inside a formula node. My LabVIEW version is 5.1.The input and output from/to formula node do not necessarily being array. Thank you.

You need to declare a variable to be an array. To declare a multidimensional array of 32 bit intergers enter this:

int32 VarName[x][y];

Where x=1st dimension size (rows) and y=2nd dimension size (columns). You can then operate on this like you would an array in a text based language. Try the entering the example below in a formula node.

int32 i;
int32 y[5][2];
for (i=0;i<5;i++)
y[i][1] = x[i]+1;

Where y is an output and x is an 1D array input.

Hope this helps...

Thank you Mr.Brian. I have tried but it does not work. the error I get is
#int32 i; ...
Is it because I am using version 5.1 or there is something that I do not understand using the declared data type. Please if possible provide me with the working vi. Thank you again.

Not really sure why it isn't working. I think that it should work in 5.1 as well. Try adding an output terminal for i, you don't need to wire it to anything. Let me know if that works.
